Effect of use two types of plows on growth components and yield of wheat in nineveh Province North of Iraq

Abstract EN

A field experiment was conducted during the agricultural season 2012 - 2013 in clay soil to study the effect of use two types of plows on on growth components and yield of wheat, two varieties ( Begal and sham 6) and two types of plow (mold board and disc plow ) with three replicate used, The characteristic studded in experimen.

, Plant height, length of spike, number of seeds per spike, Number of spikes per unit area, weight of 1000 kernel, yield of wheat RCBD design, SAS program used to analysis the experiment, begal variety was surpassed on plant height, spike length, and yield.

Disc plow was surpass on plant height, spike length, number of spike -1, and yield The interaction shown the variety bigal with disc plow gave the best result in plant height, spike length, harvest index and yield which it gave 1817.8 kg /h.
